Re: Noise levels at Flying fields
Vettster, it may be one person or two with personal agendas. However, I just had my hearing checked, and there is significant upper-end (higher frequencies) loss. For me, it's getting older. So you can see where I'm coming from on the topic of noise as I'm protecting what I do have left.
MAAC regards noise as a serious threat to the ability to have clubs close to residential areas, hence they've had the committee in existance since the 1980s. Continuously challenging ourselves to meet the requirements and being held to them by everyone else in the club (noise control officer or not) is part of the process. Having a set of club rules that specify the requirements is good sense. Differences in how to determine the readings and how to take them has taken place in this thread and are helpful and a big step in moving the original poster and his club along. It's a good thing that clubs are putting measures in place. However, they do need enforcement (that is, someone charged with making sure the program works and having the authority from the club's executive to make it stick.) Whoever is given the job (suggesting the vice-president who is probably the field manager as well) should report on who was tested, what the scores were, and who got red-flagged. That would serve several causes: enforcement seen to be happening, what the actual levels are, and who the real bad boys are. Historica comment -- This is going back about six or so years to when I was a member of the Aurora club -- there were some members who were totally against the enforcement aspect of the noise rules. Big gas engines, flew at odd times during the day when there were few people around, and the neighbours did complain to the town which got the executive involved ( was on the Executive around that time and did attend the Council presentations, which included commentary on noise levels and controls). Since I haven't been a member of the club for years, not sure if they've changed their ways or have gone on to other clubs or activities or just got swept under the rug. |

As for the Aurora club, Yes there was one incident that a neighbor complained (I forgot about that one) He was an alcoholic that moved into the decrepit old house 1/2 a mile away. He also showed up with his Rottweiler and threatened to sic the dog on everyone. The police dealt with him in timely manor and the owner of the house evicted him. Once he moved out, the house was condemned. |

Re: Noise levels at Flying fields
Just limit the number of people flying at the same time! ie if the club allows 4, only 2 fly. If there is a loud plane only one! Just try to limit the ammount of planes in the air! Also the guys make a good point with muffler and prop choices! Also for glow, try to run 4 strokes!

Re: Noise levels at Flying fields
@ shortkut: Like me, not everyone has the coin for a nice sounding quieter 4 stroke, BUT, with that said you do make a simple problem disappear by proposing a "flying Db restriction". One way it can be done, is to have an overall noise level limit for each flying field appropriate to it's surroundings. Then each plane is tested and given a Db number, then you can decide on which planes go up at the same time in accordance with the "Db Zoned" airfield.

Ahhhhhh.... where did I ever make that sort of comment? Better get your facts right before you start throwing comments like that around. I never said what you're trying to make it sound like I did. I never said that everyone had to stop flying "noisy" airplanes, just live within the posted club rules and the MAAC guidelines. BTW, EDF models can produce high-Db sounds that can easily exceed the 98Db/7 Meters rules in place at many clubs. Get your facts rights in the first place. Mouthing off like that solves nothing except to make you look like you're getting all defensive and not willing to carry on a civil and intelligent discussion. To get the facts entirely correct: I tried electrics, found that I like it and had less to carry around when I went out to the field. That's why I shifted to electrics and has nothing to do with IC motors. I left the Aurora club at about the same time because I found that attending meetings and seeing the back-biting and politics going on against the then-current executive by a small group of members made me not want to be associated with that particular club -- the fun simply went out of the hobby when I went to either meetings or the field. I went elsewhere and found TEMAC which did not have the inbred politics and cliques going on. Fact. This is the one and only time that I have said anything negative about the Aurora club publicly. People join and seem to enjoy the club. I didn't, so I exercised my rights and went elsewhere where I come home from meetings and the field with a smile on my face not knots in my stomach. BTW, I would have been more than willing to have discussed this matter privately (email or such), but you posted the nasty remark that I had to put straight. Aplologies if you're shocked, but not making a response when people post remarks like yours is not in my nature. BTW2, end of this conversation. If you want to continue it, use the message facility. |

Re: Noise levels at Flying fields
When we get noise complaints from neighbours, with only one exception since I have been the chairman of our noise control committee, the complaints arise from someone flying an airplane with a gasoline engine. Modern glow engine silencers seem to do an excellent job. Large gassers emit a lower frequency sound, which travels farther. I would be interested in hearing ideas that anyone has to reduce gas engine noise.

Re: Noise levels at Flying fields
This is a very old thread but since you asked.... I fly large gas powered planes and there are several well proven ways to keep the noise down to levels that fit within Club and municipal dB levels.
1. Throw away the stock “mufflers” that come with most gas engines and invest in a good canister or tuned pipe system. 2. Use a smaller diameter three blade prop. This will help keep those prop tips below the speed of sound. 3. Learn to use the throttle and avoid those full speed level passes that ‘rip’ the prop. My DA200 quad on canisters and a three blade prop is much quieter (on the ground and in the air) than a DA85 on stock mufflers.
